Glass vs. Glass (Translucent)

In Plane-Maker you will see that there are two "glass" lighting modes for instruments - one called "glass" and the other called "glass (translucent)".

What's the difference?  The difference is how they respond to their lighting rheostat being turned down.

• Glass becomes dim by mixing the RGB colors of the overlays toward black.
• Glass (tranlsucent) becomes dim by mixing the alpha channel of the overlays toward transparent.

Which one do you want?  It depends on what you are doing.  The rules I suggest are:

• Use "glass" if you are using the layer as a "mask" to block elements behind it.
• Use "glass (translucent) if you are using the layer as an "overlay" to draw on top of other elements.
